A water jet discharging from a $4 \mathrm{~cm}$ diameter orifice has a diameter of 3.5 $\mathrm{cm}$ at its vena contracta. The coefficient of velocity is defined as the ...

In open channel flow, the specific energy is the total energy per unit weight of a liquid, where the component potential energy is measured from the bed of the channel as...

Two reservoirs are connected by a pipeline consisting of two pipes '$\text{A}$ ' and '$\text{B}$ ' in series. The two pipes are of same length and have the same Darcy fri...

A $900 \mathrm{~mm}$ internal diameter sewer is laid at a slope of $0.004$ and has an actual flow of $0.15 \mathrm{~m}^3 / \mathrm{s}$. Assuming Manning's roughness coeff...

A $10$ million litres per day $\text{(MLD)}$ sewage treatment plant $\text{(STP)}$ is based on the Activated Sludge Process $\text{(ASP)}$. First, the sewage undergoes pr...

A venturimeter along with a differential manometer was installed to measure flow in a water pipeline as shown in the following figure (not drawn to scale).Taking specific...

Two reservoirs having a difference of $10 \mathrm{~m}$ in their water surface elevations are connected by a pipeline (diameter $=10 \mathrm{~cm}$, length $=50 \mathrm{~m}...

The depth of flow (in m, rounded off to two decimal places) in a hydraulically efficient rectangular channel $(n=1 / 80)$ to carry a discharge of $64 \mathrm{~m}^{3} / \m...

Clean water is passed through a bed of uniform spherical sand at a filtration velocity of $0.002 \mathrm{~m} / \mathrm{sec}$. The sand grains are $0.4 \mathrm{~mm}$ in di...
